Contact rpm measurement
1. Fit contact adaptor into the Tachometer and ensure a good click fit connection.
2. Start machine and make clean contact with the shaft end.
3. Ensure a steady firm pressure is applied to the wheel, just sufficient to maintain slip free contact,
excess pressure will wear the rubber tip and bearings and may slow the machine down and give
inaccurate readings.
4. Releasing the On / Off switch will hold the reading automatically for 1 minute.
Linear contact speed measurement - Metres/minute
1. Fit contact adaptor as above.
2. Press and hold the On button, then press the program button, the display will alternate between the
"rpm and mt" symbols, release the program button when the "mt" symbol is illuminated, the
instrument is now in the metric linear speed.
3. Keeping the On button pressed, now place the contact wheel on the moving surface and read the
linear rate.
4. Releasing the On button will then hold the last reading in the display for 1 minute.
5. The instrument retains Metres/min ode for continued linear measurements for up to 1 minute from
previous reading, by pressing either "Measure" buttons this mode will be held for a further minute.
6. The instrument will automatically revert to rpm mode after auto switch off.
Note: Inverted Operation, the instrument can be used through 180 deg. rotation (e.g. with the light
beam or contact probe pointing downward into a machine), the display inverts so display reading is
clear.
